Is a window just a window - a frame with or without glass - or is it much more than that? For me a window is not only a multi functional part of an architectural structure, a car or a train. It is something that has to be cleaned if it doesn't want to loose its transparency, which gives the window that special possibility of looking into the public space and giving someone in that space the chance to peer into a private one - if the window isn't hiding behind curtains, shutters or sunshades.

But a window is also a metaphor, giving it a life of its own. The window becomes a mirror, a reflection, a pattern, a portrait, a symbol of human feelings, a story.

Here is a list of the various phenomena of a window - but please keep in mind that it is far from complete.
